我使用Jonathon Fernyhough 的 PPA在 Ubuntu 16.04 上安装了 Python 3.6：
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
我使用新的文字字符串插值创建了一个字符串，但我提供了一个无效的格式说明符。我不仅得到了预期ValueError: Invalid format specifier，也得到了意外ModuleNotFoundError: No module named 'apt_pkg'。

我将此报告给Python 错误跟踪器。那里注意到：
这似乎是供应商的问题，而不是 CPython 本身。同样的问题也发生在 Ubuntu 16.10 的 Python 3.6 中。引发任何异常都可能导致：

最后，这个问题被评论关闭了
是的，这似乎是供应商的故障报告基础设施出现故障。为什么他们想要在交互式提示下的每个回溯报告都超出了我的范围，但这似乎是他们正在尝试做的事情。
我现在的问题是：
- 我如何解释这条评论？在这种情况下，供应商是 Jonathon Fernyhough 的 PPA 吗？他是否对他分发的 Python 代码进行了一些更改，以便它尝试为每个产生回溯的异常提交报告？
- 我需要通知谁或者我需要在哪里提交错误来解决这个问题？
